Filter paper is arranged between the upper cover plate and the lower cover plate, the oleophylic hydrophobic filter paper, a flow guide pipe and a filter screen are sequentially arranged between the upper cover plate and the lower cover plate from outside to inside, the flow guide pipe is connected onto the upper cover plate, an oil water separation area is formed between the flow guide pipe and the lower cover plate, a water discharging hole communicated with the oil water separation area is formed in the lower cover plate, a downstream area for oil and water to pass through is formed between the flow guide pipe and the inner side of the filter paper, and an upstream area for oil and water to pass through is reserved between the flow guide pipe and the filter screen. The multilayer filter element structure has the advantage that small water granules in diesel is condensed into large and small water drops through the filter paper, the aim of separating the oil and the water is achieved by utilizing the downstream flowing and upstream flowing in the flow guide pipe and different specific gravities of the oil and the water, the oleophylic hydrophobic filter screen can filter the water drops continuously to achieve the aim of secondary filtering, and the multilayer filter element structure is good in whole filtering effect.
Description
Technical field
The utility model relates to a kind of filter cleaner, especially relates to a kind of multi-layered filtering element structure with filter cleaner of oil-water separating function.
Background technique
Diesel-oil filter is the class in fuel filter, it is a kind of device of other impurity of sneaking into for filtering diesel oil, wherein filter core plays the effect of filtering diesel oil, the filter core of diesel-oil filter adopts filter paper to make more, for solid impurity, filter paper can filter by paper filter element micropore wherein, but, for liquid impurity, only depends on filter paper effectively not filter.
At present in diesel oil except fixing impurity, also be mixed with a large amount of small water particles, these water particles can enter motor car engine with diesel oil, can cause potential threat to the reliable running of diesel engine, can reduce the working life of diesel engine, be in particular in following three aspects: the first, make diesel engine for the precise motion couple in system in the semi-dry friction state, aggravated the wearing and tearing of precision pair; The second, cause oil supply system parts and cylinder corrosion; Three, class that Water dissolve salt, the salt after dissolving is difficult for being removed by filter, and the precision pair of salt corrosion cylinder and oil supply system can cause the earlier period damage of parts.For the filtration of water particle in diesel oil, still there is no at present effective solution.
A kind of diesel-oil filter element now is provided, as notification number is: a kind of diesel-oil filter element that the Chinese model utility of CN202207502U provides, comprise the filter core body, described filter core body comprises refill and refill lid, described refill is rolled into cylindrical making by crepe tissue, refill is loaded in the refill lid, between refill and refill lid, by the resin mighty bond, adheres to, and on the end face of described refill lid, is evenly distributed in several through holes.This diesel-oil filter element consists of filter paper, can only be for filtering the solid particle of diesel oil, and, for the water particle in diesel oil, still can enter in motor with diesel oil, the reliable running of diesel engine is caused to potential threat, and can reduce the working life of diesel engine.
The model utility content
The utility model is mainly can not filter water particle for existing diesel-oil filter element is existing, affects the problem of engine reliable running, a kind of simple structure is provided, can effectively carries out oil-water separation, and the multi-layered filtering element structure of the good filter cleaner of filtering effect.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of multi-layered filtering element structure of filter cleaner, comprise upper cover plate and lower cover plate, be provided with filter paper between upper cover plate and lower cover plate, be provided with successively from outside to inside the filter paper with oleophilic drainage characteristic between described upper cover plate and lower cover plate, honeycomb duct and filter screen, honeycomb duct is connected on upper cover plate, form the oil-water separation district between honeycomb duct and lower cover plate, lower cover plate is provided with the weep hole be communicated with the oil-water separation district, form the descender that can pass through for profit between honeycomb duct and filter paper inner side surface, leave the up district that can pass through for profit between honeycomb duct and filter screen.This filter core adopts multi-layer structure, and the filter paper that outermost one deck adopts has the characteristic of oleophilic drainage, can, the small water particle in diesel oil, be agglomerated into large droplet.Diesel oil and large water drop, arrive the oil-water separation district through descender, in this process, because oil and the proportion of water there are differences, the globule will be precipitated to below, diesel oil will float over globule top, under the effect of follow-up diesel oil, diesel oil after filtration will continue through up district, carry out secondary filter through filter screen, flow out finally by the filter cleaner oil outlet, and the globule be deposited in below diesel oil will enter through the weep hole on lower cover plate water storehouse, reach the purpose of oil-water separation with this, and filtering effect is good.The existence of honeycomb duct, make fluid first flow downward and upwards flow, reaches the inertial separation effect of the material that density is different.
As preferably, described upper cover plate comprises fixed plate and connecting plate, and fixed plate is provided with the groove that filter paper is installed, and connecting plate is L-shaped, connecting plate is connected on the inner edge of fixed plate and fits tightly with fixed plate, forms the cavity that honeycomb duct is installed between fixed plate and connecting plate.
As preferably, described honeycomb duct is circular, and honeycomb duct is connected in the cavity between fixed plate and connecting plate, and is adhesively fixed by the solid glue agent.
As preferably, the length of described honeycomb duct be between upper cover plate and lower cover plate total distance 70～85%.
As preferably, described filter screen is that the high order that scribbles polytetrafluorethylecoatings coatings is counted nylon wire.The high order that scribbles polytetrafluorethylecoatings coatings is counted nylon wire, has very strong oleophilic drainage characteristic, can keep off the side at filter screen to remaining droplet, plays the purpose of secondary filter.
As preferably, described upper cover plate is provided with the first seal ring, and lower cover plate is provided with the second seal ring.
1), filter paper is the small water particle in diesel oil, is agglomerated into large droplet, utilizes the descending and up of honeycomb duct, utilizes profit proportion difference, realizes the purpose of oil-water separation therefore, the beneficial effects of the utility model are:; 2), the filter screen of oleophilic drainage characteristic can continue to filter the globule, plays the purpose of secondary filter, integral filter is respond well.
